Summary particle size information for a lithology, such as the mean, modal,equivalent, minimum and maximum grain size, as text descriptors or numeric values.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
